VirtualTree, Abbrevia, Orpheus, PowerPDF and SynEdit now available for XE4

Posted by on in Blogs
Roman Kassebaum just let me know that several popular open source component sets are now available for Delphi, C++Builder and RAD Studio XE4 including TurboPower Abbrevia (compression toolkit), Orpheus (UI toolkit), PowerPDF (PDF file generation), SynEdit (multi-line edit control), and VirtualTree (Delphi TreeView control). You'll find links to the open source project home pages below.

Abbrevia, Orpheus, PowerPDF and SynEdit are hosted at Sourceforge. VirtualTree is hosted at Google Code. For additional information and file downloads, please go to each of the project home pages.

Big thanks to Roman, Mike Lischke, Craig Peterson, Alkis Georgopoulos and Dean Harmon for their work and support of our products!

    All our Synopse Open Source libraries are also perfectly compatible with Delphi XE4, for both Win32 and Win64 platforms.
    Main problem was the switch of some ANSI routines from SysUtils to System.AnsiStrings - this was indeed a breaking change.
    Everything else was perfectly compatible, when compared to XE3.
    Nice work!

    Mainly used components are the mORMot framework (high performance RESTful SOA/ORM set of classes), and the SynPDF library.

    Great to hear the news about the Synopse libraries supporting Delphi XE4. Thank you for your continued support of Delphi.

    Regarding the language and types moving forward, we definitely want to continue modernizing the Delphi language and runtime. At the same time, we fully understand and take care in making decisions knowing that some will have impacts on millions (billions?) of lines of Delphi code. There are times, especially with platform support, when we need to make specific changes.

    Unicode strings was the most impactful change in recent history for sure (but we needed to do it and 2009 was that moment in time we had to get it done). Adding Unit Name Scoping was another lesser impact but has really helped everyone work with framework agnostic RTL units (devices, sensors, etc) as well as allowing VCL and FMX to keep moving forward.

    In looking at the years of Delphi code, the architectures we are supporting, the different platforms, we also know learn that we need to refactor parts of the code to continue to move forward. Sometimes this means splitting apart units. Other times it means creating new units or moving functions to their proper place.

    I want to assure everyone that any change that has an impact is totally talked through, researched, reviewed, revisited, debated and more before the final decisions are made. One of the healthy and helpful things about developers is - they will give us feedback 24x7, all along the way and in every way possible. Keep it up! We are all in this together.

    Since I'm not the admin of the synedit project I'm not allowed to update the zip file. Otherwise I already would have updated it.

    The Abbrevia download on Sourceforge does not contain the XE4 package.
